Thirty-year-old graduate student Michael Powell filed an objection to a court that refused to award him the $1.5 million insurance money from the death of his brother and his nephews. Then he leapt to his death from the 7th story of a parking lot in Minneapolis, Minnesota.

Michael was an outspoken supporter of his brother, who killed his two sons, ages 7 and 5, with a hatchet, then blew up his house in Washington state in February of 2012. Josh Powell was also a suspect in the disappearance of his wife, Susan Powell, who he claimed went missing while he took a camping trip with his sons and was last seen at the family’s Utah home on December 6, 2009.

Michael also supported his father, Steve Powell, who was convicted in May 2012 on 14 counts of voyeurism after secretly taking photos of two girls who lived near him.

Michael was engaged in a bitter battle over the $1.5 million insurance policies Josh had taken out on himself and his sons with Susan Powell’s parents. Four months before the explosion of Josh Powell’s home, he changed his insurance policy, changing the beneficiary to Michael from his wife Susan.
